Application led September 11, 1926A. Serial No.134,859.

lthird to provide a rotary burner which may be driven with a minimum amountof power, and it consists essentially of the arrangement and construction of parts as hereinl after more particularly explained.

ig. 3 is a perspective view of one of the rota members showing it in an inverted position, and, l

Fig. 4 is a fragmentary perspective vien of one of the supports and a portion of the coacting rotary atomizing member mounted thereon.

In the drawing like characters of reference indicate corresponding parts in each figure.

2 is a tubular standard having a hollow base 1 of cone shaped formation and formed integral therewith. The tubular standard 2 and base 1 form a housing for the oil conduit hereinafter described. The tubular standard 2 is provided at its lower end with an external annular shoulder 1x and at its upper end with an internal annular shoulder 1. 3 is a tubular shaft forming an oil conduit extending upwardly through the centre of the standard 2 and base 1 and adapted to rotate therein. The lower end of the shaft 3 is supported by and mounted within a footstep bearing 4 as indicated by dotted lines in Figure 1, such bearing being suitably packed tol prevent any leakage of oil therefrom. 5 and 6 are a pair of ball races respectively situated intermediately of the height of and at the top of the shaft 3 and constituting bearings therefor, the bearing ,6 being mounted on the shoulder 1 so as to form a hanger support for the shaft 3. The upper end of the shaft 3 extends upwardly beyond the bearing 6 and is provided at its up 'er end with angularly upwardly inclined ra ially extending oil emitting nozzles 7 8 is a rotatable v'aporizing member in thel form of a conically dished plate which is secured centrally to the nozzles 7 so as to rotate with the shaft 3, and a plurality of radially extending pairs of inner and outer vanes 9 and 10 extending downward from the lower face of the aforesaid plate. 20 is a vaporizing member coacting with the member 8 and comprising an annular plate spaced apart and parallel with the plate 8 and provided Withupwardly extending` vanes 18 and 19. The member 20 is rotatable in an opposite direction'to the member 8, the annular paths of the plates 9 and 10 being closely adjacent to the paths of the vanes 18 and 19 extending parallel therewith.

1l is an open ended cylindrical casing spaced apart from and surrounding the standard- 2 and `plate 8. 13 is an annular member forming a pulley surrounding the bearing 14 mounted on the shoulder 1". 12 is a plurality of arms mounted on the pulley 13 and inclining outwardly and upwardly therefrom to. form a support for4 the member 11 and curving inwardly at their upper ends to form a support for the member 20.

The upper portions 15 of the arms 12 are curved inwardly and downwardly and upon which is mounted the Vaporizing member 20, the extreme ends of the portions 15 being mounted upon the outer ring '16 of a ball race 17 surrounding and secured to the upper end of the standard member 2.

The pairs of downwardly extending vanes 9 and 10 are adapted to pass between the upwardly extending vanes 18 and 19 as the vaporizing members 11 and 20 are rotated in opposite directions. The vanes 19 are provided with inwardly extensions 21 ada ted to break up any oil passing downwardly towards the sha-ft 3 and' at the same time causing an upwardly auxiliary across the face of the nozzle 7.

22 is a pulley secured to the shaft 3 in proximity to its lower end for rotating the same and the burner member formed by the plate 8 and vanes 9 and 10. 23 is an electric motor suitably positioned in the vicinity of the burner mechanism. being of course exterior to the furnace casing, and 24 is a crossed endless belt connecting the pulley22 with a pulley 25 secured to the shaft of the motor 23. 26 is a pulley also secured to the shaft of the motor 23 and connected by a belt 27 to the pulley 13 for rotating the member 20 and the vanes 18 and 19` thereof. The

driving belts 24 and 27 being wound in opdraft of air the pulleys 25 and 26 serve to rotate the atomlzingmembers 11 and 20 in opposite directions.

In order to provide a current of air to the oil as it is atomized I provide the following device.

28 are blades mounted upon the downwardly inwardly extending portion of each arm 12. These yblades are secured to the arms by means of straps 29 which pass around the arms and are adjustably secured to the blades b set screws or any other suitable means. he provision of these straps permits the angularity of the blades to' be altered to give the particular volume of air current required. Y

30 is the main oil feed pipe leading from the oil reservoir tank (not shown), such tank can be positioned, at any desired elevation to give the required head of oil. The burner end of the oil pipe 30 is suitably con- 'nectcd to the oil conduit bearing 4 so that the oil freely flows from the pipe through the bearing into such conduit and from thence up to the nozzles.

The operation of my device is as follows:

When it isdesired to put my burner into operation, oil is permitted to fiow from the 011 reservoir tank along the oil pipe 30 and through the conduit 3 up to the nozzles 7 the electric circuit connecting with the motor 23 is then closed to start the motor which through the medium of the belts 24 and 27 rotates the plates 8 and casing 11 in opposite directions as before l described. As the downwardly extending sets of vanes 9 and 10 are mounted upon the lower face of the coneshaped disc.' 8 they will be rotated in one direction together with the oil conduit 3 and attached nozzles 7 and as the casing 11 is supported upon the arms 12 the upper curved ends of which carry the sets of vanes 18 and 19 such vanes will rotate in the opposite direction to the sets of vanes 9 and 10 passing therebetween as before described. 'lhe blades 28 carried upon the arms 12 will of course also rotate and create an upward draught-of a'ir through the casing 11 which ,will mingle with the oil vapor ejected from the nozzle 7. When the burner mechanism has been rotated for a short period in .order to give the oil an opportunity to freely flow a light is applied to the upper end of the casing 11 when the oil vapor Will immediately burst into flame and continue burning as it is ejected.

By the provision of the sets of vanes ro- -tating in the opposite direction to one another it will be readily appreciated that the oil upon passing from the nozzles 7 into the space through which vanes 9 and 10 and oppositely travelling vanes 18 and 19 travel will be broken up and finely atomized before reaching the periphery ofthe disc 1l Where it bursts into flame.

By the provision of ball races at all points of rotation and by the light yet strong construction of 7my device it will be seen that a motor of comparatively small horse power will only be required to operate the burner and also by making my device of simple and compact construction I have devised an oil burner which can be readily installed in any standard type of furnace without the necessity of making any alterations, furthermore by mounting the plates 28 so that they are capable of adjustment I have devised means whereby the volume of air blast can be altered to suit the supply and consistency of the oil and thus a flame of any desired heat can be obtained. By the use of my particularly eflicient means for insuring the complete mechanical vaporization of the oil it will be appreciated that hydrocarbon fuel of any density can be successfully used.
